FILTER.

Specification of Letters Patent.

Patented New. ao, aait.

Application filed August 24,1917. Serial No. 187,991.

To all whom t may concer-n:

Be it known that I, HENRY KERSHAW, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Filters, of which the followingis a specification.

The filter which is the subject matter of the present a-pplication forpatent is designed more particularly for use in connection withmotorcycles and cars for the purpose of assuring a clean supply ofgasolene t0 the carbureter, the filter being interposed in the pipe lineleading from the gasolene supply tank to the carbureter. A

The invention has for its object to provide 'a simple and eflicie'ntfilter of the kind stated, which can be readily installed, and whichisso constructed that it can be easily taken apart for cleaning,repairs, etc.

With the object stated in view. the invention consists in a novelcombination and arrangement of parts to be hereinafter de'- scribed andclaimed, and in order-that the same may be better understood referenceis had to the accompanying drawing, forming a part of thisspecification.

In the drawing,

Figure 1 is a perspective view of the filter;

Fig. 2is a central vertical section thereof; and Figs. 3 and 4 are crosssections on the lines 3-3 and 4 4, respectively, of Fig. 2.

Referring specifically to the drawing, 5 denotes a filtering vessel inthe form of an upright cylinder having a closed bottom 6 and a topclosure 7, the latter being a screw cap. The cap 7 does not seatdirectly over the top of the vessel 5, but is detachably connected to aneck 8 carried by the latter. This neck is a ring having top and bottomreduced portions which are screw-threaded, the for- 111ery receiving thecap, and the latter beingscrewed into the top of the vessel, the partsbeing thus all separably.connected. x

The bottom 6 of the vessel 5 is provided with an inlet nipple 9 forconnection to the gasolene line, and it is also fitted with a drain cock10.

In the vessel 5 is mounted and fitted snugly therein, a glass cylinder11', :the side of the vessel has an opening 12 exposingv said cylinderand forming a sight opening through which the fluid level in the vesselmay be observed. The glass cylinder seats on the bottom of the vesseland it is held in the vessel by the neck 8, the bottom edge of thelatter having an inturned marginal Iflange 13 seating on the top edge ofthe cylinder. Thus the lglass rcylinder is `firmly held when the neck 8is screwed down on the vessel. Between the top edge of the neck 8 andthe under side of the cap 7 is interposed a gasket 14. The outer surfaceof the cap isy formed square to permit app lication of a Wrench or othertool for putting on or taking ofi' the cap.. y

In the neck 8 snugly fits a sleeve 15 the same resting on the flange 13and being kept from turning in the neck by a cross bar or pin 16 whichprojects at its ends from the outer periphery of the sleeve to seat inver tical grooves 17 in the wall of the neck on the inside therof.

In the sleeve 15 are mounted two strainer disks 18 of ine gauze, with athick felt pad 19 therebetween.

Above the top strainer disk 18, the sleeve 15 has a side aperture 20registering with an outlet nipple 21 on the neck 8. to which nipple isconnected a piping which leads to the carbureter. As the cross bar 16prevents the sleeve 15 from rotating, the aperture 2O remains inline'with the nipple 21.

The gasolene line from the supply tank (not shown) is connectedtotheinlet nipvple 9, and said tank being positioned above ythrough thestrainer disks 18 and pad 19,

and thence escaping through the outlet 20, to be carried to thecarbureter. By its passage through the water the gasolene will berelieved of heavy dirt particles, and a further straining action takes?place when the gasolene passes through the strainer elements 18 and 19,the latter intercepting and holding any water which may be present inthe gasolene, and thereby assuring isolation of water if thetwo liquidsshould be 4agitated by excessive jar so as to splash the water to thestrainer elements. The Asediment collecting in the bottom of the vvesselcan be run out by opening the drain cock 10. The entire apparatus canalso be Now `when the gasolene l cleaned out by removing the sleevewhich can be readily done aftertaking the cap 7 0E. ll claim :M 1.Afilter comprising a vessel having a bottom inlet and adapted to hold aWash liquid, 'and having an outlet above the liquid level, a neckattached to the top of the ves sel and having an internal flange, asleeve in the neck and seating on the Hange, a cap closing the neck andengaging the vsleeve to .hold the same seated on the flange, and ascreen carried by the sleeve, said screen being located between the topof the liquid and the outlet of the vessel.

2. A filter comprising a vessel having a bottom inlet and adapted tohold a Wash liquid, and having an outlet above the liquid level, a neckattached to the top of the vessel and having an internal flange, asleeve in the neck and seating on the flange, a cap closing the neck andengaging the sleeve to hold the same seated on the flange, a screencarried by the sleeve, said screen being le anaemia cated between thetop of the liquid and the outlet of the vessel, the sleeve having anescape aperture in alinement with the outlet, and means for locking thesleeve against rotation. l

3. A. filter comprising a vessel having a bottom inlet and adapted tohold a Wash liquid, and having` an outlet above the liquid level, a neckattached to the top of the vessel and having an internal flange, asleeve in the neck and seating on the flange, a cap closing, the neckand engaging the sleeve to hold the same seated 0n the flange, a screencarried by the sleeve, said screen being. located between the ton of theliquid and Athe outlet of the vessel, the sleeve having an escapeaperture in alinement with the outlet, and pins projecting from the sideof the sleeve, the interior of the neck having grooves in which the pinsseat to hold the sleeve against rotary movement.
